Underpaid $10/hour for 3 years — How Much Back Pay?
Calculate how much you are owed in back pay if you have been underpaid by $10 per hour for 3 years.
If you've been underpaid, your employer must back-pay the difference plus 12% super on the shortfall. There's no time limit on claiming wages owed, but the Fair Work Ombudsman recommends acting within the 6-year limitation period to preserve your claim.
You are owed approximately $63,726.00 in back pay
Based on $10 per hour underpayment over 3 years (38 hours/week = $380.00/week underpaid), plus estimated interest at 5% p.a.
Estimate only — interest is at a court's discretion and is not automatically payable.
Total Back Pay Calculation
| Underpayment rate | $10 per hour |

Time Limits — 6-Year Limitation Period
Important: Under the Fair Work Act, you can claim back pay for up to 6 years from the date you lodge your claim. Any underpayment older than 6 years is statute-barred and cannot be recovered.
Your underpayment period of 3 years is significant. Act immediately to preserve your full claim and prevent any further losses.
How to Claim Your Back Pay — Step by Step
- Gather your evidence: Collect payslips, timesheets, rosters, bank statements, and your employment contract. The more documentation you have, the stronger your claim. Screenshot any relevant messages or emails.
- Check your award or agreement: Use our Award Finder to identify the correct Modern Award and minimum rates for your job classification and level.
- Raise it with your employer in writing: Send a formal letter or email outlining the underpayment, the period, and the total amount owed. Many employers will rectify underpayments voluntarily once notified. See our template letter below.
- Contact the Fair Work Ombudsman: If your employer refuses to pay or does not respond within 14 days, lodge a complaint at fairwork.gov.au or call 13 13 94 for free advice.
- Small Claims Court: For claims under $100,000, apply to the Small Claims division of the Federal Circuit and Family Court. You do not need a lawyer. For larger claims, you may need legal representation — many employment lawyers offer a free initial consultation.
